Area code 236 vs 672
236 and 672 are overlay codes: they cover the same ground in British Columbia, and a number in one is a local call to the other. 236 is the original, in service since 2013. 672 was added in 2013 because the first was filling up – that is what an overlay is for. Today 236 has 746 of 800 blocks assigned (93.2%) and 672 has 324 of 800 (40.5%), so a new number in the area now almost always comes from 672. In the 33 days to 30 October 2026, 236 drew 532 FTC complaints against 34 for 672 – 200th and 392nd of 422 ranked codes. Older codes are spoofed more because they look more established. Neither code is better or safer than the other. They are the same geography, the same carriers and the same dialing rules; the difference is only how long each has existed and how full it is.

Frequently asked
What is the difference between area codes 236 and 672?
None geographically – they overlay the same area, so the difference is age and how many numbers are left.
Do I need to dial the area code between 236 and 672?
Yes. Overlay areas use ten-digit dialing for local calls, including between the two codes. Seven digits reaches a recording.
Will a new number be 236 or 672?
Whichever has blocks left – currently 672, at 40.5% allocated against 93.2% for the other. Carriers draw from the code with free blocks, which is why the newer code spreads over time.
Is 236 or 672 more likely to be a spam call?
On the complaint data, 236 appears more often. But spoofing drives those counts, so this is about which code gets imitated, not which numbers are real.
